6.1 Clinical

Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Common Adverse Reactions The safety of liraglutide injection in patients with type 2 diabetes mellitus was evaluated in 5 glycemic control, placebo-controlled trials in adults and one trial of 52 weeks duration in pediatric patients 10 years of age and older. The data in Table 1 reflect exposure of 1,673 adult patients to liraglutide injection and a mean duration of exposure to liraglutide injection of 37.3 weeks. The mean age of adult patients was 58 years, 4% were 75 years or older and 54% were male. The population was 79% White, 6% Black or African American, 13% Asian; 4% were of Hispanic or Latino ethnicity. At baseline the population had diabetes for an average of 9 years and a mean HbA 1c of 8.4%. Baseline estimated renal function was normal or mildly impaired in 88% and moderately impaired in 12% of the pooled population. Table 1 shows common adverse reactions in adults, excluding hypoglycemia, associated with the use of liraglutide injection for the treatment of type 2 diabetes mellitus. These adverse reactions occurred more commonly on liraglutide injection than on placebo and occurred in at least 5% of patients treated with liraglutide injection. Overall, the type, and severity of adverse reactions in pediatric patients 10 years of age and older and above were comparable to that observed in the adult population.

Other Adverse Reactions Gastrointestinal Adverse Reactions: In the pool of 5 glycemic control, placebo-controlled adult clinical trials, withdrawals due to gastrointestinal adverse reactions, occurred in 4.3% of liraglutide injection-treated patients and 0.5% of placebo-treated patients. Severe gastrointestinal adverse reactions were reported more frequently among patients receiving liraglutide injection (1.2 mg 4.4 %, 1.8 mg 4.2 %) than placebo (1.1 %). Withdrawal due to gastrointestinal adverse events mainly occurred during the first 2 to 3 months of the trials.

Injection site reactions: Injection site reactions (e.g., injection site rash, erythema) were reported in approximately 2% of liraglutide injection-treated adult patients in the five double-blind, glycemic control trials of at least 26 weeks duration. Less than 0.2% of liraglutide injection-treated patients discontinued due to injection site reactions.

Hypoglycemia: In 5 adult glycemic control, placebo-controlled clinical trials of at least 26 weeks duration, hypoglycemia requiring the assistance of another person for treatment occurred in 8 liraglutide injection-treated patients (7.5 events per 1,000 patient-years). Of these 8 liraglutide injection-treated patients, 7 patients were concomitantly using a sulfonylurea.

In a 26-week placebo-controlled clinical trial in pediatric patients 10 years of age and older with a 26-week open-label extension, 21.2% of liraglutide injection-treated patients (mean age 14.6 years) with type 2 diabetes mellitus, had hypoglycemia with a blood glucose <54 mg/dL with or without symptoms (335 events per 1,000 patient years). No severe hypoglycemic episodes occurred in the liraglutide injection treatment group (severe hypoglycemia was defined as an episode requiring assistance of another person to actively administer carbohydrate, glucagon, or other resuscitative actions).

Papillary thyroid carcinoma: In adult glycemic control trials of liraglutide injection, there were 7 reported cases of papillary thyroid carcinoma in patients treated with liraglutide injection and 1 case in a comparator-treated patient (1.5 vs. 0.5 cases per 1,000 patient- years). Most of these papillary thyroid carcinomas were <1 cm in greatest diameter and were diagnosed in surgical pathology specimens after thyroidectomy prompted by findings on protocol-specified screening with serum calcitonin or thyroid ultrasound. Pancreatitis In glycemic control trials of liraglutide injection, there have been 13 cases of pancreatitis among liraglutide injection -treated patients and 1 case in a comparator (glimepiride) treated patient (2.7 vs. 0.5 cases per 1,000 patient-years). Nine of the 13 cases with liraglutide injection were reported as acute pancreatitis and four were reported as chronic pancreatitis. In one case in a liraglutide injection-treated patient, pancreatitis, with necrosis, was observed and led to death; however clinical causality could not be established. Some patients had other risk factors for pancreatitis, such as a history of cholelithiasis or alcohol abuse.

Cholelithiasis and cholecystitis: In adult glycemic control trials of liraglutide injection, the incidence of cholelithiasis was 0.3% in both liraglutide injection- treated and placebo-treated patients. The incidence of cholecystitis was 0.2% in both liraglutide injection-treated and placebo-treated patients.

Laboratory Tests Bilirubin: In the five adult glycemic control trials of at least 26 weeks duration, mildly elevated serum bilirubin concentrations (elevations to no more than twice the upper limit of the reference range) occurred in 4% of liraglutide injection-treated patients, 2.1% of placebo-treated patients and 3.5% of active-comparator-treated patients. This finding was not accompanied by abnormalities in other liver tests. The significance of this isolated finding is unknown.

Calcitonin: Calcitonin, a biological marker of MTC, was measured throughout the clinical development program. At the end of the adult glycemic control trials, adjusted mean serum calcitonin concentrations were higher in liraglutide injection-treated patients compared to placebo-treated patients but not compared to patients receiving active comparator. Between group differences in adjusted mean serum calcitonin values were approximately 0.1 ng/L or less. Among adult patients with pretreatment calcitonin <20 ng/L, calcitonin elevations to >20 ng/L occurred in 0.7% of liraglutide injection-treated patients, 0.3% of placebo-treated patients, and 0.5% of active-comparator-treated patients. The clinical significance of these findings is unknown.

Lipase and Amylase: In one adult glycemic control trial in renal impairment patients, a mean increase of 33% for lipase and 15% for amylase from baseline was observed for liraglutide injection-treated patients while placebo-treated patients had a mean decrease in lipase of 3% and a mean increase in amylase of 1%. The clinical significance of elevations in lipase or amylase with liraglutide injection is unknown in the absence of other signs and symptoms of pancreatitis. Vital signs Liraglutide injection did not have adverse effects on blood pressure. Mean increases from baseline in heart rate of 2 to 3 beats per minute have been observed in adult patients treated with liraglutide injection compared to placebo.

6.2 Postmarketing

Experience The following additional adverse reactions have been reported during post-approval use of liraglutide injection. Because these events are reported voluntarily from a population of uncertain size, it is generally not possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

G astrointestinal: Acute pancreatitis; hemorrhagic and necrotizing pancreatitis sometimes resulting in death; ileus, intestinal obstruction, severe constipation including fecal impaction, nausea, vomiting and diarrhea leading to dehydration H epatobiliary: Elevations of liver enzymes, hyperbilirubinemia, cholestasis, cholecystitis, cholelithiasis requiring cholecystectomy, hepatitis Hypersensitivity: Angioedema, anaphylactic reactions, pruritus N eoplasms: Medullary thyroid carcinoma Neurologic: Dysgeusia, dizziness, dysesthesia P ulmonary: Pulmonary aspiration has occurred in patients receiving GLP-1 receptor agonists undergoing elective surgeries or procedures requiring general anesthesia or deep sedation.

Renal: Acute renal failure or worsening of chronic renal failure, sometimes requiring hemodialysis; and increased serum creatinine Skin and subcutaneous tissue: Cutaneous amyloidosis, alopecia
